libtool: Extend fix-final-rpath.patch

When building upower from meta-oe, the following QA error occurred:
ERROR: QA Issue: package upower contains bad RPATH

It appears to have been caused by one of the cases fix-final-rpath.patch
is meant to address but missed. So this change fixes the additional case
that was causing upower to have the QA error.
